There are several grades of steam , each offering very different levels of contamination risk. Reimers makes electric boilers to meet many applications
of steam quality. Electric Steam Boilers
Plant steam is the lowest grade of steam and therefore has the highest risk of potential contamination. The levels of contamination arising
from using plant steam are determined by the following factors: • The quality of raw water entering the boiler. • The level of chemicals being dosed
into the system and adherence to a water treatment management program. • The correct operation of the boiler. • Cross contamination from other processes.
Filtered steam, also known as culinary steam, is plant steam that has passed through a fine stainless steel filter, typically of five
microns pore size. The potential risk of contamination from boiler water treatment chemicals and cross contamination still remains when using a culinary
filter. The amount of contamination that finds its way past the filter will depend upon the severity of the problem, the nature of the maintenance
regime and the velocity of the steam.
Clean steam is the highest grade of steam for food and beverage applications and is typically raised from purified water in a dedicated
clean steam generator. Clean steam should be considered for critical processes. See Reimers Electric boiler options Bakery Saturated Steam Boilers
Pure steam is the pharmaceutical industry’s development of clean steam. The quality and purity of pure steam is in excess of that required
for the food and beverage industry today.
